Yagi Castle (八木城, Yagi-jō) is a late Kamakura period Japanese castle located in the Yōka neighborhood of the city of Yabu, Hyōgo Prefecture, Japan. Its ruins have been protected as a National Historic Site since 1997.[1] The ruins are regarded as historically important, as the site includes the traces of a Kamakura period feudal mansion, Muromachi period mountain castle with clay walls, and the ruins of a Sengoku period castle with stone walls.
